abstract

This paper proposes an inter-domain routing algorithm for multi-domain WDM networks based on hierarchical PCE architecture. The proposed algorithm presents a strategy of selecting k random paths in parent PCE. The simulation indicates that the proposed algorithm outperforms previous methods in term of blocking probability and resource utilization.
